  At this time, the surfaces of the wheels CA1 and CA2 are cleaned by the brush bristles 42. Moreover, the wash water W is sprayed from the gaps between the brush hairs 42, and the recesses and the tire house of the wheel CA2 are washed.

  When cleaning the lower part of the vehicle CA to be cleaned other than the wheels CA1, the wheel brush 41 is separated from the vehicle CA to be cleaned, and only the cleaning water W is sprayed from the first nozzle part 45 and the second nozzle part 46. The vehicle to be cleaned CA may be cleaned.

  According to the present embodiment, the lower cleaning device 35 injects the cleaning water W from the injection nozzle disposed on the wheel brush 41 to the vehicle CA to be cleaned while the wheel brush 41 is rotating. For this reason, the surface of the wheel CA2 of the wheel CA1 can be cleaned by the brush bristles 42. Further, the recesses and the tire house of the wheel CA2 can be cleaned with the cleaning water W. Thereby, the cleaning power can be improved.

  Further, since the spray nozzle has the first nozzle portion 45 arranged at a position eccentric with respect to the shaft 44 (rotating shaft), the washable range of the lower cleaning device 35 can be expanded, for example, the spoke of the wheel CA2 Even if the gap is small, it can be washed.

  Further, since the injection nozzle has the second nozzle portion 46 disposed on the shaft 44 (rotating shaft), the cleaning power at the center portion of the wheel CA1 can be improved.

  In addition, since a plurality of the second flowing water channels 48 are formed and the plurality of inlets 44a are opened in the peripheral surface of the shaft 44, the cleaning water W can be efficiently injected into the vehicle CA to be cleaned.

(Second Embodiment)
Next, a second embodiment will be described. In the present embodiment, the cleaning operation by the lower cleaning device 35 is different from the first embodiment. Others are the same as in the first embodiment.

  The user drives to stop the vehicle to be cleaned CA in front of the remote panel 7A, and sets the car wash conditions for the vehicle to be cleaned CA from within the vehicle to be cleaned CA.

  After setting the car wash conditions, the user moves the to-be-washed vehicle CA to a predetermined washing start position. Then, the car wash machine main body 1 moves in the front-rear direction, straddles the vehicle to be cleaned CA, and cleaning with the top brush 4 and the side brush 5 is performed.

  FIG. 6 is a flowchart showing the operation of the lower cleaning device 35 of the car wash machine WA of the second embodiment. In step S <b> 1, it is determined whether or not the wheel CA <b> 1 of the vehicle to be cleaned CA is arranged in front of the lower cleaning device 35 by the advance of the car wash machine body 1. When the wheel CA1 of the vehicle to be cleaned CA is arranged in front of the lower cleaning device 35, the process proceeds to step S2. When the wheel CA1 of the vehicle to be cleaned CA is not disposed in front of the lower cleaning device 35, the process waits until the wheel CA1 of the vehicle to be cleaned CA is disposed in front of the surface of the lower cleaning device 35.

  In step S2, cleaning by the lower cleaning device 35 is started. In the cleaning by the lower cleaning device 35, the wheel brush 41 rotates and the brush bristles 42 are cleaned away from the wheel CA1, and high-pressure cleaning water W is sprayed from the first nozzle portion 45 and the second nozzle portion 46 to thereby clean the wheel CA1. Wash. At this time, for example, the wheel brush 41 rotates at a high speed of 140 rpm. Since the wheel brush 41 performs cleaning by high-speed rotation, more cleaning water W can be sprayed onto the surface of the wheel CA2.

  In step S3, a timer is activated. Thereby, the elapsed time from the start of the high-speed rotary cleaning in step S2 is measured by the timer.

  In step S4, the wheel brush 41 starts to advance toward the wheel CA1. In step S5, the process waits until a predetermined time elapses from the start of advancement of the wheel brush 41. When a predetermined time determined from the speed at which the wheel brush 41 advances and the estimated distance with respect to the wheel CA1 has elapsed, it is determined that the wheel brush 41 has contacted the wheel CA1, and the process proceeds to step S6.

  In step S6, the wheel brush 41 stops advancing. In step S7, the wheel brush 41 rotates at a low speed and the brush bristles 42 come into contact with the wheel CA1 for cleaning, and the high-pressure cleaning water W is sprayed from the first nozzle portion 45 and the second nozzle portion 46 to clean the wheel CA1. To do. At this time, the wheel brush 41 rotates, for example, at a low rotational speed of 90 rotations / minute, and cleans the wheel CA2 for a predetermined time. Since the wheel brush 41 rotates at a low speed for cleaning, damage to the tip of the brush bristles 42 can be suppressed even if the wheel brush 41 comes into contact with the wheel CA1.

  In step S8, the rotation of the wheel brush 41 is stopped, and in step S9, the wheel brush 41 moves backward. In step S10, the lower cleaning device 35 determines whether or not the cleaning of the rear wheel wheel CA1 is finished. If cleaning of the wheel CA1 of the rear wheel of the vehicle CA to be cleaned remains, the process proceeds to step S1 and steps S1 to S9 are performed on the rear wheel. When the cleaning of the rear wheel wheel CA1 is completed, the cleaning operation of the lower cleaning device 35 is ended.

  Thereafter, air is blown from the top blow nozzle 21 and the side blow nozzle 22 toward the vehicle CA to be cleaned, and the vehicle CA to be cleaned is dried.

  According to the present embodiment, the rotation speed (140 rotations / minute) of the non-contact wheel brush 41 facing the wheel CA1 is larger than the rotation speed (90 rotations / minute) of the wheel brush 41 that contacts the wheel CA1. For this reason, the wheel brush 41 that is not in contact with the wheel CA1 is rotated at a high speed while spraying the cleaning water W from the spray nozzle (the first nozzle portion 45 and the second nozzle portion 46), thereby improving the cleaning power of the wheel CA1. Can do. Moreover, since the wheel brush 41 which contacted the wheel CA1 rotates at low speed and the wheel CA1 is washed, the damage of the wheel brush 41 can be suppressed.

  Further, since it is determined that the wheel brush 41 has contacted the wheel CA1 when a predetermined time has elapsed since the start of advancement of the wheel brush 41, the car wash machine WA having the above configuration can be easily realized.

  Moreover, in this embodiment, it replaces with the elapsed time from the advance start of the wheel brush 41, and when the advance stroke of the wheel brush 41 becomes larger than a predetermined value, it judges that the wheel brush 41 contacted the wheel CA1. Also good.

(Third embodiment)
Next, a third embodiment will be described. In the present embodiment, unlike the second embodiment, the car wash machine WA detects the contact state between the wheel brush 41 and the wheel CA1 by a current detection unit (not shown) that detects the drive current of the wheel brush 41 instead of the timer.

  FIG. 7 shows a flowchart showing the operation of the lower cleaning device 35 of the car wash machine WA. In step S <b> 1, it is determined whether or not the wheel CA <b> 1 of the vehicle to be cleaned CA is arranged in front of the lower cleaning device 35 by the advance of the car wash machine body 1. When the wheel CA1 of the vehicle to be cleaned CA is arranged in front of the lower cleaning device 35, the process proceeds to step S2. When the wheel CA1 of the vehicle to be cleaned CA is not disposed in front of the lower cleaning device 35, the process waits until the wheel CA1 of the vehicle to be cleaned CA is disposed in front of the surface of the lower cleaning device 35.

  In step S <b> 3, detection of the drive current value flowing through the wheel brush 41 is started by the current detection unit. In step S4, the wheel brush 41 starts to advance toward the wheel CA1.

  In step S5, it waits until the drive current of the wheel brush 41 becomes larger than a predetermined value. When the wheel brush 41 comes into contact with the wheel CA1, the driving current of the wheel brush 41 increases. For this reason, if the drive current of the wheel brush 41 becomes larger than a predetermined value, it will be judged that the wheel brush 41 contacted the wheel CA1, and it will transfer to step S6.

  At this time, you may vary the rotational speed of the wheel brush 41 at the time of contact with the wheel CA1 with the shape of the wheel CA2 of the wheel CA1. In general, when the wheel CA2 of the wheel CA1 has a spoke type shape, the tip of the brush bristles 42 is washed while being sandwiched between the spokes during washing. For this reason, the contact resistance of the wheel brush 41 during washing is larger in the spoke type shape than in the dish type shape. Accordingly, the wheel brush 41 is more likely to be damaged in the wheel CA1 having the spoke type wheel CA2 than in the wheel CA1 having the dish type wheel CA2. Further, the wheel CA1 having the spoke-type wheel CA2 has a larger driving current for the wheel brush 41 than the wheel CA1 having the dish-type wheel CA2.

  For this reason, you may make the rotation speed of the wheel brush 41 larger than when it is large when the drive current value after the wheel brush 41 contacts the wheel CA1 is smaller than a predetermined value. Thereby, the detergency with respect to the wheel CA1 having the dish type wheel CA2 can be improved. Further, it is possible to more reliably prevent the wheel brush 41 from being damaged when the wheel CA1 having the spoke type wheel CA2 is cleaned.

  Note that the shape of the wheel CA2 may be input in advance by operating the remote panel 7A or the operation panel 7, and the rotation speed of the wheel brush 41 may be varied according to the shape of the wheel CA2.

  In step S6, the wheel brush 41 stops advancing. In step S7, the wheel brush 41 rotates at a low speed and the brush bristles 42 come into contact with the wheel CA1 for cleaning, and the high-pressure cleaning water W is jetted from the first nozzle portion 45 and the second nozzle portion 46, and the wheel is driven for a predetermined time. Wash CA1.

  In step S8, the rotation of the wheel brush 41 is stopped, and in step S9, the wheel brush 41 moves backward. In step S10, the lower cleaning device 35 determines whether or not the cleaning is finished.

  Thereafter, air is blown from the top blow nozzle 21 and the side blow nozzle 22 toward the vehicle CA to be cleaned, and the vehicle CA to be cleaned is dried.

  According to the present embodiment, it is possible to improve the cleaning power and prevent the wheel brush 41 from being damaged, as in the first embodiment. Further, since it is determined that the wheel brush 41 has contacted the wheel CA1 when the drive current value of the wheel brush 41 has become larger than a predetermined value, the rotation of the wheel brush 41 according to the contact state of the wheel brush 41 with respect to the wheel CA1. The car wash machine WA whose number can be changed can be easily realized.

  Moreover, since the rotational speed at the time of contact with the wheel CA1 is varied according to the shape of the wheel CA2 of the wheel CA1, damage to the wheel brush 41 and the wheel CA2 can be suppressed.

  In the second embodiment, the rotational speed of the wheel brush 41 when contacting the wheel CA1 may be varied according to the shape of the wheel CA2 as described above.

  According to the present invention, it can be used for a car wash machine provided with a lower washing device.
